Casting resin prism test

Unfortunately, this mock-up only worked in the almost pitch-black environment, where I couldn't  video capture due to the lack of light source. 

I have been wondering if the holographic projection film would make any differences to improve this mock-up. ( ex. Placed the film on each side of glass prism, then proceed to resin casting process.)
